This is a collection of links to my favorite sites selling miniatures useful for naval gaming.1/2400 WWII, and 1/2400 WWI which includes some pre-dreadnought-era vessels that were still active in WWI. Proportions of many models are be a bit odd, masts and cranes are fragile, assembly of tiny parts can be very fiddly and frustrating, and details are greatly exaggerated for the scale, but these have some of the greatest visual impact of any miniatures in this scale. The oversized details also make these extremely easy to paint using simple techniques like washes and drybrushing. A properly painted GHQ 1/2400 warship can be stunning to look at.
1/1200 Napoleonic sailing vessels, with extremely nice proportions and crisp details.
1/1200 vessels for the Napoleonic Wars, Anglo-Dutch Wars, American Civil War, Renaissance Mediterranean, Ancient Mediterranean, War of 1812 Great Lakes fleets, and 18th Century Baltic navies (mostly the unusual and unique Russian and Swedish small craft for coastal and shallow water operations).
1/200 WWI coastal boats and floatplanes.
1/300 ancient galleys and (smaller) Napoleonic vessels.
1/2400 WWII and WWI, very clean sculpts, and nice white metal castings. Probably the best proportions and scaled detail in white metal, but gun barrels tend to be very thin and therefore very fragile. Some of the WWI cruisers are a bit small, but generally these miniatures are scale-compatible with other 1/2400 manufacturers.
1/4800 WWII. If that sounds too small, take a look at these photos and see if you change your mind. For many years, this incomplete line from C-in-C was the only offering in this scale, but recently there are zillions cropping up on Shapeways, so now you can build huge fleets of very small ships for WWII gaming.
1/2400 WWII, WWI, pre-dreadnoughts, post-WWII, including a very large and impressive selection of civilian and auxiliary vessels.
Sculpting quality is highly variable, though few are really bad. Most castings for eras up through WWI and many of the warships in the interwar and WWII periods are a bit "melted", crudely detailed, and tend to have somewhat odd proportions, but many of the WWII civilian and auxiliary vessels and the post-WWII vessels are simply brilliant, matched only by GHQ and WTJ. That said, I still find many of the cruder castings delightful and find they look pretty nice if painted and dressed up carefully.
Began as a manufacturer of 1/3000 white metal pre-dreadnought era vessels, and still produces those.
Expanded into 3D printing and now offers a growing line of pre-dreadnought and WWI vessels and shore batteries in plastic, and you get to pick your scale. The cheapest scales are 1/3000 and 1/2400, but all the 3D prints can also be ordered in 1/1800 and 1/1500, and now a few have started to appear in 1/1250 and 1/1000 scale. Note that the cost of the models rises dramatically as the scale goes up.
1/1200 scale ancients, Renaissance, Age of Sail and ACW naval.
1/3000 scale Anglo-Dutch Wars, Napoleonic naval, and steam-era vessels from about the ACW up through the Cold War.
Both scales include some bits of shore terrain, mostly harbor stuff. You can't build an entire city, but you can make the docks of a port.
Navwar has to have the most complete line of miniature vessels in existence, not only including vast numbers of unique, rare and civilian vessels, but also "what if" and "almost were" vessels. The castings tend to be crude, but functional and very cheap.
Navwar is a venerable member of the wargaming community. This shop may not be around much longer; the owner is in his 80s and scaling back. Hopefully he'll sell the molds and masters to someone else to carry on when he's done.
1/2400 ACW through the modern era.
These are very plain, gray, epoxy castings. They are extremely tough and durable, but take considerable dressing up to look nice. They are also somewhat overscale and don't mix well with the same ships from other manufacturers, so if you're going to add Panzerschiffes to a fleet made by a mix of manufacturers, make sure all the vessels of the same class are either Panzerschiffe or not Panzerschiffe.
1/3000 scale WWI, WWII and modern naval.
1/600 Renaissance galleys, Armada ships, and a pretty large range of ancient ships (both galleys and sailing craft).
Some larger scales of niche period stuff, like 1/350 moderns, 1/700 MTBs, etc.
There used to be more, but much of it was sold off to save the company after a financial crisis.
Nothing Skytrex sells is very high quality, and it tends to be a bit pricey for what you get, but I admit I like the Armada period ships once I do a few customizations and paint them nicely.
Former Skytrex ranges of 1/1200 Napoleonic sail, ACW naval and transitional sail/steam ships (steam-powered wooden 2- and 3-deck ships of the line, frigates, sloops, some ironclad frigates, etc.)
Sells the 1/1000 scale post-ACW through pre-dreadnought models from the old Houston's Ironclads line of naval miniatures.
The Houston's models are only vaguely in scale, some are oddly proportioned, and they aren't perfectly accurate, but they are delightful artistic renderings of the weird and unique ship designs of the long transitional era between the ACW and the dreadnought era. They come with just enough detail to be nice eye candy, and benefit immensely from better masts, boats, davits, and other add-ons. They also look better in person than the photos on the Great Endeavors site.
Sells the 1/1000 scale ACW models from the old Houston's Ironclads line of naval miniatures. All the comments about the Great Endeavors 1/1000 models apply.
Note that this site adverstises these as 1/1200 scale, but that is inaccurate, and the models will not mix with 1/1200 ACW naval sold by other manufacturers. If you decide to invest in the Houston's ACW ships, you will have to complete your project with them or scratch build additions.
Too many to list and more added all the time, so I made a whole page of links to Shapeways shops I like.
